Abstract: Systems and methods for monitoring of biometric and contextual variables to assist in screening for, quantification of, and prediction of smoking behavior, and for assisting in smoking cessation are described.

Abstract: Methods and systems of enhancing an electronic interaction between a behavioral-modification program and a user in the program by providing customized content specific to the user. The systems and methods allow for coach-counselor assistance to the individual-user or for automated content delivery.

Abstract: Breath sensor apparatus and methods of use are described herein where a flow control apparatus may generally comprise a sampling chamber defining a volume and one or more openings into the sampling chamber, at least one sensor in fluid communication with the sampling chamber, wherein the at least one sensor is configured to detect the analyte. The sampling chamber may also be configured to receive the breath sample into the sampling chamber and into contact with the at least one sensor via diffusion into the sampling chamber.

Abstract: Breath sensor calibration methods and apparatus are described herein where a breath sensor device may generally comprise a sampling unit having a housing configured to receive a sample breath from a user and a sensor positioned within the housing. A processor in electrical communication with the sensor may be configured to determine a dissipation time when the sensor is exposed to a near-constant concentration level of CO detected from the breath sample down to an ambient level of CO detected. The processor may also be configured to calculate a time constant based on the dissipation time and a reduction from the near-constant concentration level to the ambient level. Furthermore, the processor may also be configured to apply the time constant to a transient response of the sensor to account for drift in calibrating the sensor.

Abstract: Breath sensor measurement methods and apparatus are described. One variation may generally comprise a sampling unit having a breath sampling port, at least one pressure sensor located within the sampling unit and in communication with the breath sampling port, and a processor in communication with the at least one pressure sensor. The processor may be configured to prompt a user with instructions to exhale a sample breath for a first predetermined period of time into the breath sampling port and to inhale for a second predetermined period of time through the breath sampling port. The processor may be configured to measure a pressure change via the pressure sensor over the first and second predetermined periods of time such that the processor determines a total volume of air corresponding to lung capacity of the user based on the pressure change over the first and second predetermined periods of time.
